IMPROVEMENT IN HAY AND COTTON PRESSES.

. X Specitieation ibi-ming part of Letters Patent No. 33,365, dated July QS, 1863.

To all whom it may concern:

Be it known that I, I. O. INGERSOLL, of Green Point, in the county of Kings and State of New York, have invented a new and use- `,ful improvement in arrangement and construction of toggle-levers to raise and lowerthe followers of hay, cotton, and other presses; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l Vis a plan view of apress with the top removed; Fig. 2, a longitudinal elevation with one side removed.

A is the frame of the press, to which is secured guide-rods B B', which guide and control grooved friction-rollers O upon the ends of levers D, which levers are hung at their centers to frame A by levers E. Platen or follower F is attached to levers D by rods and joints G to pivots II, that secure friction-roll` ers O to levers D. Friction-rollers I upon the lower ends of lever Dare secured and heldin place by leversK and pivots L. Grooved friction-rollers llI are held firmly to frame A by arched stirrup N and axles O O.

l? are ropes or chains to operate the press.

Q, Q are stirrups for securing platen or top door, R, in its position.

Operation: rlhe ropes I)` may be'worked (by a wheel, a eapstan, or in any known way) to operate levers D and E, that move the follower F. f

The arrangement of levers D and E upon both ends of the press, and the arrangement and attachment of the levers to each other and to the frame A and follower F, in the p0- sition and proportion shown, possess advantages over any heretofore constructed for the purposes designated.

.Vhat I claim as my invention, and desire to secure by Letters Patent, is-

Connecting the levers D D to each end of the follower F by means of the two connecting-rods and joints G G, and also controlling the movement ot' the lsaid levers by the friction-rollers H H, and the outside rods, B B, as shown, and for the purposes before speci` iied.
